Poetry and other writing of Katherine Philips and Katherine Thomas are reproduced here in association with the Perdita Project based at the University of Warwick and Nottingham Trent University, from manuscripts at the National Library of Wales. "Perdita" means "lost woman" and the aim of the Project has been to identify and describe all manner of manuscript writing by early modern women from diaries to works of drama.
